Abstract
Objective
To study the characteristics and tendency of incidence of patients with respiratory system tumors during the past 23 y in Tianjin.
Methods
All data in our research was obtained from the surgical pathology files of Department of Pathology of the general and the Second Hospitals of Tianjin Medical University between 1981 and 2003. All data was analyzed by Spss 11.5 statistics program. The comparisons were made by u-test, P<0.05 was considered as significant.
Results
1. The detection rate of malignant tumors is significantly higher than that of benign tumors (U=52.68, p=0.000) in respiratory system. 2. The common sites of benign tumors are nose and pharynx, but the common sites of malignant tumors are lung and larynx. 3. The incidence of benign tumors generally peaks between the ages of 40 and 50, but the incidence of malignant tumor generally peaks between the ages of 50 and 60. 4. The commonest histological type of malignant tumors is squamous cell carcinoma, but the commonest histological type of benign tumors is papilloma. 5. The detection rate of malignant lung tumors steadily increased between 1981 and 1999 and increased sharply from 1999 to 2003, but the detection rate of malignant Nasopharyngeal tumors steadily decreased from 1981 to 2003. Between 1981 and 1997, the detection rate of malignant laryngeal tumors steadily increased, followed by a decrease between 1997 and 2003.
Conclusion
The detection rate of malignant respiratory system tumors especially lung cancer is gradually increasing. Therefore early prevention and treatment are critical to patients’ prognosis.
